SUPPORT FOR WINDOW-SASHES.

SPECIFICATION forming part of Letters Patent No. 571,551, dated November17, 1896. Application filed November 13, 1895. erial No. 568,751. (Nomodel- T0 (tZZ whont it may (lo/worn:

lie it known that l, LUZEENE M. BoLLEs, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Supports for\VindowSashes, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts.

This invention relates to improvements in supports for window-sashes,and the object thereof is toprovide improved means whereby the sashes ofa window may be revolved on their supports, so as to provide means forthe proper ventilation of apartments, a further object being to providesliding stiles or bars by which the window-sashes are supported, saidstiles or bars being provided with countcrbalance-wcights by means ofwhich they, together with the window-sashes which are pivotallyconnected therewith, maybe raised or lowered to any desired point; andwith these and other objects in view the invention consists in theconstruction, combination, and arrangen'ient of parts hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aside elevation of a windowframe, together with the window sashes mountedthereon, said window-sashes being supported according to my inventionand a portion of the construction being shown in section; Fig. 2, asection on the line 2 2 of Fig. 1, showing the outer sides of the stilesor bars between which the window-sashes are pivoted, one of said sashesbeing tilted on its pivots; Fig. 3, a section on the line 3 3 of Fig. 2;Fig. 4., a section on the line 4 4 of Fig. 5; Fig. 5, a section on theline 5 5 of Fig. 1; Fig. 6, a vertical section through a portion of theframe, a portion of one of the sliding stiles or bars, and a portion ofone of the sashes, showing the construction of one of the springsemployed in connection with the sliding stiles or bars; Fig. 7, asimilar section showing the means by which the sliding stiles or barsare supported, and Fig. 8 a side view of said stile or bar.

In the drawings forming part of this appli cation, A represents theusual side bars of a window-frame, ii the top thereof, and (.1 the hbottom, and the sides A are provided with the usual beads or strips 1),E, and F, between which the separate sashes are mounted and in thepractice of my invention I support the separate sashes of the window,which are shown at G and II, in the following manner: The separatevertical beads or strips D, It, and F form two vcrti'cal spaces, and ineach of these vertical spaces I place vertically movable stiles or barsIt, two being employed in connection with each sash, one on each sidethereof, and these stiles or bars are preferably of the same length asthe windowsashes with which they are connected, and secured to thesestiles or bars are the cords or chains L by which they a re supported,said cords or chains being connected with weights (not shown) by whichthe stiles or bars and the window-sashes are counterbalanced in theusual manner. In connecting these chains or cords with the stiles orbars K, I form in the outer sides of the upperends thereof verticalslots or grooves M, as shown in Figs. 7 and 8, and at the lower ends ofthese slots or grooves M, Lset intcsthe stiles or bars a circular platem, the upper side of which is cut away, so as to form an angular notchor recess m, and said circular plate m is provided on its lower edgewith an inwardly-dirccted se mental flangc m and at each side of theangular notch or recess m with inwardly-directed lugs or shoulders m andthe chains or cords L are secured in place by means of a cross-bar m,which is passed behind these shoulders or projections m as shown inFigs. 7 and 8.

Each of the stiles or bars K is provided on its outer side and near itsupper and lower ends with spring-operated plates N, set into oblongslots or recesses it, formed in the sides of the-stiles or bars. Theouter surface of these plates is beveled at the upper ends thereof, asshown at n, and the inner surface thereof is beveled at the lower end,as shown at a and the lower ends of said plates are secured to thestiles or bars by a screw a or in any preferred manner.

Secured to the inner side of the free or upper end of the plates N is aninwardly-dil't-cttttl. cylinder it, which passes through the stile orbar, and formed around the same is an annular chamber, in which ismounted a spiral spring if, the object oi. which is to force the plate Noutward against the sides A of the window-Frame, and thus Force thestiles or bars inwardly.

lhe sash-frames are pivotally connected with the stiles orbars Kattherenter thereof, as shown at O in l igs. l and L, and this pivotalconnection ismade in the following manner: The vertical sides of thesash-frames are provided on their outer surfaces withlongitudinalgrooves l, which may be of any desired shape incross-section, and the adjacent surfaces of the stiles or bars h. areprovided with corresponding longitudinal beads onbeveled portions I",which are adapted to fit therein, and sunk into thcsides of the sashesin the bottom of the longitudinal grooves l are plates R, which areprovided centrally with outward iy-directed cylindrical extensions R,which extend part way through the stiles or bars K, as shown in Figs. 4.and 5, and said stiles or bars K are provided at this point on theirouter surfaces with cavities or recesses Ar.

Passing through the cylindrical extension 1% of the plates K arepivot-pins S, through the inner end of which is passed a pin S, whichrests in a chamber beneath the plates R, and mounted on the outer endsof said pivotpins within the cavities or recesses K is a plate 7. whichis held in place by a pin 7: and between the plate 7; and the end of thecylindrical extension R of the plate R is a spiral spring 'l.

It will be understood that the sashes are free to revolve on thepivot-pins S and between the stiles or bars K, and that said stilesorbars project beyond the beads or strips D, E, and F, and when thesashes are closed or in the normal position the said stiles or bars areforced inwardly, so that the longitudinal rib or convex portion P entersthe longitudinal groove or concave portion P of the sashes, and thusforms a close fit and airtight connection between said sashes and thestiles or bars.

The longitudinal grooves P or concave por- 'tions of the sides of thesashes may be of any desired form in cross-section, and thecorresponding longitudinal convex portion of the stiles or bars must beadapted to fit therein, and when the sashes are closed, as hereinbeforestated, these parts are forced together by the action of the springs non the plates N, as hereinbefore described, and when the sashes aretilted on their pivotal connection, as shown in Figs. 2 and 3, thestiles or bars are forced outwardly by reason of the formation of thejoint between said stiles and bars, said joint comprising thelongitudinal grooves P or concave portion of the sashes and thelongitudinal beador concave portion P of the stiles or bars.

Whenever it is desired to open or revolve one of the sashes, it is onlynecessary tocateh hold of either the lower or upper end thereol' and topull ilnvardly or shove outwardly thereon, as will be readilyunderstood, and this operation will result in turning the sash on itspivotal supports, as shown in l igs. J and I and in this operation thestiles orbars K are forced outwardly, so as to fill or nearly [ill thespace between the same hnd the sides of the window-i'ranie, and byreversing this operation the sash may be turned to the closed position,in which position the stiles or bars K will be forced inwardly by thesprings n, as hereinbefore described.

It will be understood, of course, thatch-her of. the sashes, the upperor the lower one, may be turned or revolved imlepeinlently of the other,or that both of said sashes may be turned or revolved together, and itwill be also understood that when it is desired to revolvc the lowersash it must be raised, so that the lower side thereof will be free fromthe strip or head at the bottom of the frame, and when it is desired torevolve the upper sash the same must be lowered, so that it will be freefrom the strip or bead at the top of the frame.

From the foregoing description it will be seen that the window-sashesare supported entirely and solely by the vertically-movable stiles orbars K and that these stiles or bars are provided with the usualcounterbalance weights and cords, and my invention is not limited to theexact form, construction, and arrangement of parts herein shown and dcscribed; and I therefore reserve the right to make all such alterationstherein and modi fications thereof as fairly come within the scope ofthe invention.

In the construction herein shown and dc scribed I also employ loops orstaples U, which are set into the side of the sashes II and in thebottoms of\tl1e concave portions or grooves P, and the object of thesestaples or loops is to provide a bearing-surface against which the endsof the cylinders 01 strike, as shown in Figs. 1 and 6, and which serveto press the plates N outwardly audio prevent the shaking or rattling ofthe sashes when the latter are closed.

Having fully described my invention, I claim as new and desire to secureby Letters Patentl.
